Marie Curie was a physicist and chemist who coined the term “radioactivity” and whose research into radioactive decay made her the first woman to win a Nobel Prize. The physics Nobel was followed by one in chemistry for the discovery of the elements polonium and radium.
Hours of research by our editors, distilled into minutes of clarity.
Overcoming social and academic barriers, Curie's realization that radiation resulted from an intrinsic property of atoms reframed scientific understanding of the phenomenon. Her subsequent work in discovering two new elements—polonium and radium—earned her a second Nobel Prize.
Restrictions from the Russian Empire on women's education drove Polish academics to set up illegal meetings where classes could operate in secret. Lecture locations constantly changed, keeping the university secret from Russian authorities for two decades.
Despite lacking proper laboratory conditions, Marie and Pierre built an ionization chamber and a piezoelectric quartz electrometer to measure the amount of charged particles released via radiation to a sensitivity of ten-trillionth of an ampere. Substances with different emission rates indicated different elements.
Jacques and Pierre Curie discovered the piezoelectric effect in 1880. Pierre incorporated it into an apparatus used by Marie Curie to discover polonium and radium. This phenomenon is seen in barbecue lighter ignition mechanisms, where quartz is struck to create a spark that ignites fuel.
The “petites Curies” allowed medical professionals to identify the severity of wounds without transporting soldiers to medical facilities, expediting treatment and saving lives. The efforts of Curie and other women led to expansions in their rights after the war.
Named after its founder, Robert de Sorbon, the former University of Paris was founded in 1253 to teach clerics and agents of royal and ecclesiastical institutions. The school was split into several autonomous universities after protests in May 1968.
Alongside his brother, he studied electric fields in crystals and the magnetic properties of substances, which required the construction of delicate electrometers. He would use this apparatus with Marie Curie to measure radioactive emissions and the presence of undiscovered radioactive elements.
In 1896, Henri Becquerel had been exploring phosphorescence—the emission of light of one color after an object is exposed to another color. He expected these emissions to come from objects exposed to sunlight, but he observed emissions after an overcast day.
Their discoveries of polonium and radium involved ongoing exposure to radioactive materials before shielding technology was developed. Their notebooks, furniture, and other belongings remain radioactive today, requiring researchers to sign a waiver and wear protective clothing to access.
Marie Curie's awards in physics and chemistry and Linus Pauling's in chemistry and peace are the only pairs in different fields. Awards to Curie's daughter and sons-in-law have made the Curies the most awarded family in history.
